2 answers:
Answer:
First answer is A.
Second answer is: tan.
Third is answer C. sqrt7/3
Fourth answer is A. -3sqrt7/7
Step-by-step explanation:
Answer:
Part A) Use the identity
Part B)
Step-by-step explanation:
we know that
----> by trigonometric identity
we have
substitute in the expression above
solve for tan(A)
square root both sides
Remember that Angle A terminates in quadrant IV
so
The value of tan(A) is negative
<em>Find the value of cot(A) </em>
we know that
----> is the reciprocal
therefore
simplify
